I'll have to think on that, Jaina! I feel like I should know some...there are a couple of manga drawing ones I've been thinking about getting for my son.
Another great just art basics book is Art Fundamentals: Theory and Practice, by (if I can remember this, I moved last week and it's packed up) Ocvirk, Stinson, Bone and Wigg. I've had this book since college but I know there have been many editions since then (back when dinosaurs ruled the earth, to hear my kids tell it). But it's great for learning all those technical things, like color theory, composition, light sources, perspective, etc...
I'd be interested if anyone has any great titles on watercolor techniques (or other media) as well!
